Ideal Inside of Rocket - 搜索视频

SOLVED: A certain ideal rocket with a nozzle area ratio of 2.3 and a throat area of 5 in^2 delivers gases at k = 1.30 and R = 66 ft-lbf/lbm-Â°R at a design chamber pressure of 300 psia and a constant chamber temperature of 5300 Â°R against a back pressure of 10 psia. By means of an appropriate valve arrangement, it is possible to throttle the propellant flow to the thrust chamber. Calculate and plot against pressure the following quantities for 300, 200, and 100 psia chamber pressure: (a) pressu
